Lab activities in primary and secondary education are essential to promote students' scientific skills. In this article, we propose a lab activity where different antimicrobial agents are used to the microorganisms' susceptibility to them. Moreover, we produce a rubric, a scoring tool, to quantify students' replies and evaluate the whole activity.…

To promote student involvement in the reduction of chemical waste generated by teaching laboratories, a method published by Flinn Scientific for the treatment of waste sodium molybdate has been modified for use in treating waste generated by the popular molybdenum blue method for the analysis of phosphate in natural water samples. In this teaching…

Innovative approaches to teaching genetics are essential for improving student engagement and comprehension in this challenging field. Laboratory-based instruction enhances engagement with the subject while fostering the development of practical competencies and deepening comprehension of theoretical concepts. However, constraints on time and…

Recent advancements in large language models (LLMs) hold significant promise for improving physics education research that uses machine learning. In this study, we compare the application of various models for conducting a large-scale analysis of written text grounded in a physics education research classification problem: identifying skills in…

There is increasing interest in the use of artificial intelligence technologies, which have become a transformative force in the field of education, in educational fields that include subject areas that support lifelong learning, such as science and chemistry education. In this study, a systematic review was conducted on the use and effects of…

Cell biology research methods and techniques is one of the training courses for graduate students before enter the laboratory in many universities. However, due to the limited time of experimental teaching while the teaching contents are increasing, choosing suitable teaching content has always been a challenge faced by experimental teaching.…

Despite extensive conceptualization of ions as hard spheres in most textbooks, solid-state structures are more accurately modeled as overlapping soft spheres that better reflect the size of the ions. The corresponding soft-sphere ionic radii of alkali and halide ions can be empirically established from the partial molar volume of the ions in…

We developed a remote lab experience where freshmen grew and analyzed the activity of sourdough starters as a means of engaging with chemical engineering concepts. This six-week hands-on activity was targeted due to its low-cost, non-hazardous materials, and ability to be conducted safely in a non-laboratory setting. By designing the lab to be…

To best prepare students for the real-world research environment, key skills, including experimental design, data analysis, communication of results, and critical thinking, should be key components of undergraduate science courses. Furthermore, the impact of the COVID-19 pandemic on in-person teaching has resulted in a need to develop courses that…

Introductory biology courses at most colleges and universities have two components: a lecture and a lab. However, for students who are not majoring in biology and taking the introductory course as part of their general education requirements, the distinct role of the lab has not been clearly articulated. We performed an online modified-Delphi…

The analogy among momentum, heat and mass transport phenomena is an important concept in chemical engineering education. This paper presents the analogy between heat exchanger and packed column calculations. The effectiveness-NTU method used to calculate outlet temperatures of hot and cold streams in an exchanger is introduced in a packed column…

A challenge in the pandemic era is to implement effective but flexible practical teaching for biological sciences courses. Such teaching needs to deliver conceptual, analytical and practical skills training while having the option to rapidly respond to health and safety issues, local regulations, staff and student concerns. In this paper, we…

Low-dimensional materials especially graphene-based are of high interest to a broad community. One of the most fundamental aspects in the biomedical field is material characterization, which helps understand their property and tune for application. Though the existing teaching curricula are well standardized to include basic principles and…

Cancer databases collect original cancer studies and patient clinical information into one site that allows for global analysis. While many courses focus on cancer, few utilize these powerful cancer databases. Our goal was to create a lab experience in which students could explore original cancer study databases, looking at the expression and…

Laboratory activities are a prevalent and essential part of chemistry learning because of their potential to help students develop problem solving abilities, visualize chemistry concepts learned in lecture, and gain practical skills. However, learning in the laboratory environment is not without its challenges. For example, cookbook-style…
